Requirements

  • Requires macOS 10.12 or later.
  • Calman Home, Video Pro, Studio, or Ultimate required
    • Version 5.13.0. or later.
  • Calman Supported Meter Hardware
  • Apple Built-In or External SDR display

Step 1

Welcome to the Patterns™ Calibration Workflow

  • From the Calman Menu in the top-left, choose Open Workflow Template -> Calibration and then Patterns™ Calibration
  • For Apple Built-in or External displays capable of SDR, choose Apple
    • This will configure the workflow to best support built-in or external Apple displays

Step 2

Connect Patterns and your Meter

  • To connect to Patterns, both macOS and Calman must be on the same network/subnet.
  • At launch, Patterns provides a list of available IP Addresses. If this window has been closed, go to the Patterns menu and select Show IP. Enter the IP address in the space provided.
  • Click Connect to Patterns.
    • This will automatically connect to Patterns as both a pattern generator and display device
  • Connect your meter to Calman

Step 3

Set your colorspace settings for Pre-Calibration Validation.

  • Set the target colorspace you wish to calibrate to. Then set the Patterns Colorspace to the same target.
    • For optimal performance of the display, set Patterns to 'Display SDR'.
  • In the macOS Display Preferences, Disable:
    • Automatically Adjust Brightness
    • True Tone

Step 4

Here you will measure the pre-calibration state of your selected colorspace

  • To take Pre-Calibration Measurements click the Read Series [...] button to measure the display's grayscale and ColorChecker response

Step 5

Here you will establish your targets for calibration

  • Set the desired calibration target for your display.
    • Typically, this would be the widest gamut the display is capable of; such as P3, Rec.2020, or Adobe RGB.
  • Choose the EOTF that corresponds to the display's native response.
  • Set the Patterns Colorspace to match the target colorspace.
    • Example: Target Colorspace: DCI P3, D65, Power 2.2, Patterns Colorspace: Photography (P3-D65 at 2.2)
    • For non-XDR Apple Displays (Display P3):
      • White Point: D65
      • Color Space: DCI P3
      • EOTF: 2.2

Step 6

Adjust the overall luminance of your display

  • Click the Read Continuous button to measure your display's light output at 100% white and adjust the display’s peak white to the desired luminance.
    • Luminance is a subjective target. SDR reference luminance is 100nits, but you may need to target higher to account for the ambient light in your environment.
  • Adjust your displays backlight/brightness control so your display is about 15% brighter than your final target to account for a reduction in luminance when calibrating the 1D LUT in the next step
  • Press Stop when luminance adjustment is complete

Step 7

Here Calman will perform calibration to the selected targets.

  • On the AutoCal Setup Dialog, name your ICC profile for easy identification

Step 8

It's common to lose some overall luminance following calibration, here you can verify and adjust your post-calibration luminance levels

  • Use the Read Single or Read Continous buttons in the lower right corner to measure your overall luminance and make small adjustments as needed to reach your target

Step 9

Here you will choose your colorspace for post-calibration verification

  • Choose the same target colorspace in Patterns and Calman for validation.

Step 10

Here you will measure against your chosen colorspace

  • To take Validation Measurements click the Read Series [...] button to measure the display's grayscale and ColorChecker response

Calibration Complete

  • Following Calibration, you can choose to...
    • Restart - Resets the workflow and returns to the beginning of the calibration process
    • Save Data - Saves the calibration session for later reference
    • Additional Validation - Provides ColorChecker and Saturation Sweep layouts to perform more in-depth verification
